About the area
Central London covers the six boroughs at the core of the capital: Westminster, the City of London, Camden, Islington, Kensington & Chelsea, and Southwark. The housing stock here is among the oldest and most complex in the country, with a high proportion of listed buildings, mansion blocks, and period conversions where maintenance obligations and lease structures matter as much as physical condition.

Housing stock
Georgian and Victorian terraces, mansion blocks (particularly in Kensington and Marylebone), purpose-built flats, converted Edwardian houses, and an increasing number of high-specification new-build developments. Significant listed building concentration across conservation areas including Belgravia, Bloomsbury, Barnsbury, and Primrose Hill.
Market context
Prime central London has corrected sharply since 2025, with flats and mansion-block apartments falling furthest and houses holding up comparatively better. Rental yields remain tight. Leasehold structures dominate, making title review and lease terms critical. Short leases and expensive ground rents are a recurring concern for buyers.
Market data
Central London is where the capital's correction has been sharpest, and it remains the most lease-driven, value-stratified area we cover. Activity is dominated by leasehold flats, mansion-block apartments and period conversions, where lease length, ground rent and service-charge structure often matter more to value than physical condition. In the year to July 2026 London as a whole fell 3.3% to around £550,000, but the core boroughs fell far harder: Westminster averaged about £877,000, down roughly 21% on a thin and volatile sample, Kensington and Chelsea about £1.23 million, down around 14%, Camden about £815,000, down 10%, and Islington about £675,000, down 5%. Southwark was the exception, flat at around £572,000. Flats have led the decline everywhere, so buyers of converted and purpose-built apartments have unusual negotiating room, but should scrutinise lease terms and service-charge accounts closely before relying on the headline discount.
